w. ZULK I SHOULDER PRESSING BOARD Feb. 4, 1930.

Filed May 16. 1929 INVENTOR A 'TTORNE Y Patented Feb. 4, 1930 PATENT OFFICE 1 WILLIAM J. ZULK, or PHILADELPHIA, PENNSYLVANIA SHOULDER-DRESSING BOARD Application filed. May 16, 1929. Serial No. 363,590.

My invention relates to improvements in a pressing board, and is particularly directed to a coat shoulder pressing board, and its ob] ects are to make a board substantially the shape of a persons shoulder, so that the coat will not be stretched out of shape in the pressing operation. Pressing boards must be strong 1 and rigid, and another object of my mvention is to make a board that maybe revolved 19 end for end very easily and rapidly and that may be held firmly on its base in either of its positions. Due to this ease of revolution, the board is equally useful to a right handed or a left handed person. Other objects and advantages will be apparent as the description continues.

In the accompanying drawings forming a part hereof, v Figure 1 is a top plan view of the board showing the base in dotted lines.

Fig. 2 is a front elevation thereof. 'Fig. 3 is a vertical sectional view on llne 33 of Fig. 1. f Fig. 4 is a vertical sectional view on line 3 4- 1 of Fig. 1.

' Similar numerals refer to similar parts throughout the several views.

The board 1 has upon it a padding 2, and

' the board is pivoted on abolt 3, thehead of "3 which is countersunk into the board and is w held down byplate 4 screwed to the board. I

Theboard is supported on block 5, through lwhich the bolt 3 passes to recess 6. Bolt 3 has pinned washers 7 and 8 on both sides of lever 9, through which the bolt passes, at its lower end. Lever 9 is supported pivotally, by bolt 10, fast in block 5. Springll is between a washer on the center part of the bolt against block 5 and restsupon washer 7 and it firmly holds the board down onto the block 5 Lever 12 is pivoted to the front of the block. This lever in its released position, leaves lever 9 in itslower position and the I spring efiective to hold the board down tightly. When-lever 12 is lowered, as in dotted lines in Fig. 3, it looks lever 9 up, the lever V i I I pushing the bolt 3 up against the action of w the spring and the board 1 is up as in Fig. 3

so that it may be turned end for end, then lowered by releasing the lever 12.

Block 5 should be securely bolted to a table 13, orother support, as by bolts 14. At each end of board 1 and block 5 are fixed countersunk interlocking members 15 and 16, which hold the board firmly on the block when the lever 12 permits the spring 11 to hold the board down.

I Block 5 is 'cut away at 17 to permit articles to slip further over the board.

I The board at its ends is shaped like aplan view of a persons shoulder. This shape may perhaps best be defined by the system of polar coordinates, althoughthis system is used as a medium of expresion only, the conformity of the shape of the board to the plan View of a persons shoulders being'the essential novelty, The ends, and the rearof the board from the ends, have a curve substantially like that of. one leaf of the three leaf lemniscate, which has the formula, rho=a sine 3 theta, in which rho is the distance of any point on the curve from the pole, a fixed point of the system, theta is the angle between a fixed hori zontal line through the pole and a line from the poleto the point on the curve, and"a is the length of asingle leaf of the figure, called a lemniscate. If the leaf have its pole at. the back of the board, as at 17, a central part of the board being substantially rectangular, and the large end of the leaf form the end of the board, as at 18, and'the rear edge of the leaf be substantially in line with the rear edge of the rectangular center portion of the board for a distance from the leaf pole of about the length of the leaf, as at 19, and if-the rectangular part of the board stop at that point, at both the front and back parts of the board, and if apoint 20, be taken on the front edge of the leaf which is cut by a line about-% of the length of the leaf from its pole, as at 21, and that point be joined by a wave curve as at 22, to the front of the rec- 'tangular center portion, the shape of the board will, substantially, be produced. The depth of the board at its center portion, from front to back, is substantially {7; the length of the leaf oft-he le'mniscate. This description applies to one end'of the board. The relative length of the board is immaterial except for the matter of convenience in use.

The board is designed primarily to press the top and top seam of the coat shoulder, and the coat shoulder is placed over the board end with the parts below the shoulder, that is, the sleeve and coat body, hanging downwardly from the board. The board is the shape of the plan View of a persons shoulder,

the concave front part of the board end corresponding to the hollow int-he front of the shoulder and the convex rear, part, of the board corresponding to a plan view of the scapula of a persons shoulder. This. permits. the pressing of the top front of the coat shouldernot only without bulging it outwardly,

in detail in the: form preferred by me on account of its. struc ural simplicity and economy and convenience in use. I am, however, aware that it 1s; capable of conslderable variation in structural detail without. departing from-my inventionl What I claim as new and by Letters Patent: is z; y I
